 - [x] Added per-section Rows, Grid, Compact and Bubble presentation plus one/two-column controls; normalized them in the persisted settings model and rendered them through the shared preview/PDF engine.
 - [x] Added regression coverage for the revised studio workflow and shared section presentation; full verification passes with 62 frontend suites/253 tests, 709 backend tests, TypeScript and the optimized frontend build.
 - [x] Diagnosed release 271 as self-hosted-runner instability (test-host crash, then checksum-invalid NuGet cache entries) and added bounded clean-cache restore recovery without weakening signature, build or test gates.
+- [x] Diagnosed release 273's assertion-free Node exit 139 and added a single full-suite retry only for that runner crash signature; ordinary frontend test failures remain blocking.
 - [x] Fixed fresh SQLite/MySQL startup ordering so the migration-owned UI-language column is not pre-created by schema reconciliation, then proved the full fresh-database path in Playwright.
 - [x] Visually verified the revised builder at 375 px, 768 px, and 1440 px in light/dark mode, including multiple expanded sections, add-content focus return, Customize/AI surfaces, responsive overflow, multi-page preview and searchable PDF export.
 - [x] Rechecked branch/status, recent CV work, existing tests/build tooling, and current builder architecture.
